Okay, so just to make sure I'm following you 100% here, you are talking about changing the timing of the intake cam relative to the exhaust cam by using an adjustable cam gear on the end of the camshaft (does it actually mature which camshaft the adjustable gear goes on to?). To be even more specific, you are saying it is in widening (increasing) the Lobe Seperation Angle that gives the gains. In that case, that's a relatively easy and cheap mod to do myself if I get a timing wheel and a dial gauge to calculate lobe centers (and a thousand hours to pull the engine out of the bike). Now my million dollar question, how much of an increase in LSA? (and/or what absolute number in terms of crankshaft degrees should one aim for?)
Is there much to be gained from different cam profiles? (i.e. changing valve opening and closing rates and durations etc, and just setting aside the fact that this would be a significantly more expensive mod).
On the intake side, what are most people doing, just replacing the filter with a higher flow element or are they actually changing/modifying the entire filter box?
